Adolescent fear conditioning accelerated adult reward conditioning. Averaged % time spent in the port during each reward cue was used to assess reward seeking behaviour. Over the 5 days of reward conditioning (r1-5) ADSC-F rats presented the steepest learning curve, despite insignificant baseline differences at r1 (a). This effect in the ADSC-F group was not already apparent within the first reward conditioning session (b). r1-5: reward session 1-5. i: interval, 5 consecutive reward trials were averaged to form an interval; ^####p < 0.0001, ^###p < 0.001, ^##p < 0.01 and ^#p < 0.05 vs r1 (a) or i1 (b), ^p < 0.05 vs ADSC-U of the same interval. Data are mean + SEM.
